Consequences of nonzero neutrino masses on the evaluation of the weak coupling constant and on tau leptonic decays
Journal Article

· Phys. Rev. D; (United States)
The effect of the limit of the muon-neutrino mass on the precision with which the weak coupling constant G/sub F/ can be evaluated from the experimental muon decay rate is calculated and discussed. Present limits allow an effect as large as 23 ppm. In tau leptonic decays the effects of a nonzero tau-neutrino mass amount to a decrease in the branching fraction B(tau..-->..e..nu../sub e/..nu../sub tau/) of ..delta..B/B<1.2%.
